The VISOCOLOR® reagent case for soil analysis contains all reagents, instruments and accessories required for the preparation of soil extracts and the subsequent determination of
- Ammonium, Nitrite, Nitrate (N)
- Potassium (K)
- Phosphate (P)
The soil extracts are either prepared with Calcium-Acetate- Lactate (CAL) solution (prior to the determination of P and K) or with CaCl2 solution (prior to the determination of N and pH).
If required by national regulations for soil analysis or because of local geological conditions, the VISOCOLOR® reagent case for soil analysis can also be used together with extraction solutions other than CaCl2 or CAL. Please consult instruction leaflets for possible interferences.
Reagents are sufficient for 110 CaCl2 extractions, 7 CAL extractions and 60 – 100 tests.
Shelf life of reagents: at least 18 months
